XML Digital Signature Methods

[This feature was first implemented for MSXML 5.0.]

This section describes the following methods for XML digital signatures.

createKeyFromCertContext	Creates and returns a key handle from a certificate context as defined in CryptoAPI. Both the private and public keys are accessible through the resultant key handle.
createKeyFromCSP	Retrieves a key handle from a key container within a specified Cryptographic Service Provider (CSP). This key handle is used to access the private key used for signing or the public key for signature verification.
createKeyFromHMACSecret	Extracts and returns a key handle from a base-64 encoded secret value used in the HMAC algorithm. This key handle is used to access a key that can be used for both signing and signature verification.
createKeyFromHMACSecretBinary	Creates and returns a key handle from an unencoded binary secret value used in an HMAC algorithm. The key accessible through this handle may be used for signing and verifying an XML document or fragment.
createKeyFromNode	Creates and returns a key handle based on the information contained in the `<ds:KeyInfo>` element and its descendant elements (`<ds:KeyInfo>` is a child of a `<ds:Signature>` element). The key handle is used to access the key that is used for signature verification.
createSAXProxy	Creates and returns a SAX proxy object. The `setReferenceData` method uses this object to assign a SAX stream as the new data source of the signature object or template.
getCSPHandle	Retrieves the handle to the cryptographic service provider resulted from calling the `IXMLDigitalSignature::createKeyFromCSP` method.
getStoreHandle	Gets a handle to the certificate store from which the certificate can be retrieved and validated.
getVerifyingCertificate	Retrieves the certificate associated with this key that is used in signature verification.
getVerifyingCertficateContext	Retrieves the certificate context associated with this key.
setDebugOutput	Sets the target for debug output.
setReferenceData	Assigns a new data source to a specified `<ds:Reference>` element in a signature object.
setStoreHandle	Sets a certificate store handle on the signature object, so that certificate information can be inserted into the `<ds:KeyInfo>` element.
sign	Signs data referenced in a `<ds:Signature>` element.
verify	Verifies the signature of a data referenced in the `<ds:Signature>` element.
